WILLIAM R. IJAVONS, OF CLEVELAND, OHIO.

BURNER.

l Specification of Letters Patent.

Application lled December 9, 1.907. Serial No. 406,724.

To all whom it mayconcern:

Be it knoWn that I, WILLIAM. R. J EAVONS',

a citizen of the United States, residing at Cleveland, in the county of Cuyahoga-and State of Ohio, have invented a certainneW and usefullmprovement in Burners, of which the following is a full, clear, and exact defscription, reference being had to the accompanying drawings.

This invention relates lto oil burners and more especially to burners Which are employed in heating stoves and lamps and, in

the preferred embodiment, is especially adapted for use With burners of stoves known to the trade as smokeless heaters. In

' common With burners which have been emv ployed heretofore with stoves oi `this type, it

is provided With asto vfor the wick, the stop.` bemg carried by the air distributer and being so arranged that the Wickcannot be turned beyond a predetermined height.

lIn the embodiments of my invention disclosed herein, the Wick-stop consists of a flange carried by the vertically-extending portion of the air distributer and rojecting above and across the top' of the Wic tubes in a vposition to intercept the' Wick. As the Wick rises, the flange rests on top of the wick and is carried u Ward thereby, carrying with it the air distri uter, the upward excursion of the wick being limited by a stop nut Which prevents the distributer from being raisedeyond a certain predetermined distance: In the operation of ordinary burners of this type With the heavier oils, the stop is so set that When the Wick is raised to. the highest point its top is about a quarter of an inch above the top of the Wick tubes, the area of Wickthus exposed being that adapted for vtheproduction of the maximum flame'and l the amount of Wick exposure providing 'an ample surface on the outside of the Wick for high flame that would produce smoke.

some localities, however, 'there arev 1n use Wliatare known as light oils, ,are more volatile and vaporize with less heat than dothe heavier oils above referred to.

In operating a burner with-lighter oils andhaving the stop arranged as described, 'the Wlck exposure will be too great jor suchlighter oils, excessive' vaporization .will be produced, and an excessively high and smoky flame Will result. Also in some cases the chimneys or drums when designed for some certain uses may causethe burner parts to become abnormally heated, and even with the heavier grades of oil the va ori'zationl and Patented Dec. 15, 1908.

flame will be excessive. .Wh e these objec- At ior 1able results could be overcome by so .limltlng the movement of `-thedistributer as to reduce theWickexposure, yet this Will resultin the disadvantage that the space be-v tween the top of the wick tubes and the Wick-stopping'flange Will be so small as to make it exceedingly difiicult to initially light the burner.v Furthermore, any irregularif ties of the Wick will now bear a greater proportion tothe total Wick exposure thanin the former case and Will produce relatively greater irregularities in the flame than when the wick exposure is greater.

It is the Qri'jectof this invention to maiis tain a large exposure of wick surface and'at the same time reduce the rateof vaporization from such surface where the character of the oils or the character of the device used makes it desirable to do so." 'For this purpose, I"

make use of a shield or curtain of peculiar construction, additional to the air distributer and carried thereby, which serves to inter'- cept the radiant heat of the'flame from the 'wick-stop flange, thereby lessening thevap-V orization produced at the top of thewickby suchflan e.

Generally speaking, the invention may be defined as consistin of the combinations of elements embodied 1n the claims hereto annexed -and illustrated in the drawings, Wherein- Figure 1 re resents a view, partly in section-and part y in elevation, of so, much of ar burner as is necessary to show my invention;

Fig. 2l represents a vlew similar to Fig. 1 but showing the air distributeriin vertical secf tion; and Fig. 3 re resents a vertical-sectional vi'ew of a modification of the invention .A

To the outwardlyvextending'portion 14 of the distributer there is secured a cylindrical curtain 16,"the diameterwvhereof is slightly less than the diameter of the wick flange 9 andthe lower end whereof is spaced a slight distance from said wick flange. It will be observed that curtain 16 is provided withlarger perforatioiis 'than sleeve 8, whereby said curtain has arelatively larger area of perforations than said sleeve and thus does 16 serves as'a heat interce vter whichshields the `flange 9 from! radiant eat ofy the flame,

` with the result thatsaid dange'and the top of 6 0 ow the wick are maintained atla relatively p tem' erature compared with that which they woud otherwise attain, enabling me to e m. "ploy'for light oils 'the samejamount of ,wick

.exposure as with hea oilsand at 'l time' preserve' -asmoke ess. L

ceases In lrig'. 3 I havel shown a modification of the invention illustrated in the preceding iigures. .lnthis -case the curtain 17 is frustoconical in Shape and is secured to the outwardly projecting portion 14a of the air distributer at the junction of the sleeve 8"l therewith. From this point, the curtain 17 flares downwardly and outwardly, with its' lower' end restingon top of the wick flange 9a. As is the case with the curtain shown in Figs. -1 and 2, the perforations in 'curtain 17 are larger than those in sleeve 8a, so that the 'presenceof this curtainl does not interfere l with the distijibutio'nof air through thevdisltributer, its'purpose being to shield flange@EL and the top'pf th e`wick fromv the radiant'heat of the flame i In both modifications of'rny invention disclosed herein, thereare provided simple and effective means whereby all.' of the advantages 'of large wick 'exposure-"may be 4retained with the-use of light oils or in a device having conditions for abnormal heating of the parts,

with the production of an efficient and smokeless llame therefrom. l

While I have described my invention in detail, it will be obvious that lthe details of construction may be niod'iied or varied without departing from the spirit of 'my invention,

and' hence I'do not propose to be limited to" such details except as theymay be positively included'in the claims lhereof or may be rendered necessary by thepror-state'of the art.
